I have a 1991 5.0 Convertible Mustang and the top won't go down. When you push the button, it doesn't do anything. There is no noise of a motor running or anything else, only silence. I tried replacing the fuse and that didn't help. Any suggestions would be appreciated.

I would go to the back and find the motor that operates the top and confirm that it is getting power when the switch is pressed. If it is getting power back there then chances are the motor is no good. If you get no power to the motor then the relay is probly not any good or you have a bad ground . Im not a vert guy but I have messed with some different models , they usually use an electric motor running a hydraulic pump. Ive seen the lines crack and loose all the fluid out of the pump then the motor turns but the top does nothing and some of the motors are so quiet you can only tell there running if you have someone hit the switch while your back at the motor listening.

That's not true on mine (the E-brake)... My top will sometimes glitch when I stop it greater than or less than 1/2 way (when I'm tucking material or avoiding the scissor action on the material)....The trick that usually works is to manually lift the top while operating the switch...kinda like push starting. Avoid letting the frame settle (on it's own). If I need to stop it midway, it is always best to stop it straight up...or give it a helping hand to avoid the settling. It's happened plenty of times (10+) & I've always gotten it to work...knock on wood.

ive never had to manually do anything with my top...in fact the fox mustang was praised at the time for having a top that was as fast or faster than a benz vert when it came out...like said above you need to see if you are getting power...it might just be a bad top if it was running and not moving anything i would say its low on Auto trans fluid in the top motor.

No juice to your top motor is my guess. Or the motor itself is bad, like others are saying just get a tester and test the lines going to it. I would check CL for the motor, they get pricey IIRC.

iirc the top motor is the same from 1965-2004 so they are pretty easy to find. ive seen fox vert 4 cylinder cars for 400$ could always buy one of those and get the top motor and sell the hull for scrap=free top motor and any other parts switches, wiring etc you need

MY 1990 LX has two relays, and one went out. The easy thing to do is to swap the relays around since they are plug in types. One is used for UP and one is used for DOWN. In my case a new relay fixed my problem. Good luck!

Yep - check relays first, then pull back seat and see if you're getting juice to the motor when the switch is activated. Hoping it's just a bad relay. Good luck and post back when you find out what the issue was, as it may prove helpful to someone else who is experiencing the same issue.
